Inertia Absolute URL config option

Description

Feature Request: Inertia Subdomain Navigation Support

Context:
I have a multi-tenanted application that identifies tenants using subdomains. As a result, navigating between tenants requires the use of absolute URLs instead of relative paths. Currently, when using Nuxt UI components with inertia: true, absolute URLs are not recognized as internal links. Consequently, the default behavior triggers the rendering of a standard anchor (<a>) element, causing links to open in a new tab unintentionally.

Suggested Feature:
Introduce an additional prop or option, such as inertiaSubDomain: true, to indicate that the provided absolute URL points to an internal subdomain. When enabled, this would add target="_self", ensuring the navigation occurs within the same tab via Inertia routing.

Benefit:
Many apps use subdomains like shop, admin etc. This would prevent the need to constantly add target="_self" to each subdomain link.

Additional context

No response

Start by tracing how Nuxt UI components handle links when inertia: true, especially the decision that treats absolute URLs as external. Verify the behavior with absolute URLs on tenant subdomains and define completion as same-tab Inertia navigation without requiring target="_self" on each link.
